LINE CONSTRUCTION (ELECTRIC POWER DISTRIBUTION) : Intermediate (Book with DVD) (Workbook Included)

Line Construction (Electric Power Distribution): Intermediate comprehends various diverse practical and visual skills with knowledge of specialized materials and techniques. An electric power distribution system is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. Primary distribution lines carry this medium voltage power to distribution transformers located near the customer’s premises. This book will introduce the knowledge and skills for those studying and/or working in electrical industry to interpret and convey information in response to workplace requirements.

About this Book

The information in this book consists of competencies that a person must possess to erect distribution line poles, climb pole and install pole assembly, conductors, line equipment and devices as well as to install consumer service connection facility. Line construction involves work on non-energized lines, particularly construction/ extension of new electric power distribution lines.

About the Line Construction Industry

Electric power transmission is the bulk transfer of electrical energy, from generating power plants to electrical substations located near demand centers. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. Transmission lines, when interconnected with each other, become transmission networks. The combined transmission and distribution network is known as the power grid. Line installers and repairers (also known as line workers) install or repair electrical power systems and telecommunications cables, including fiber optics. Electrical power-line installers and repairers install and maintain the power grid—the network of power lines that moves electricity from generating plants to customers. They routinely work with high-voltage electricity, which requires extreme caution. This can range from hundreds of thousands of volts for the long-distance transmission lines that make up the power grid to less than 10,000 volts for distribution lines that supply electricity to homes and businesses. Line workers who maintain the interstate power grid work in crews that travel to locations throughout a large region to service transmission lines and towers. Workers employed by local utilities work mainly with lower voltage distribution lines, maintaining equipment such as transformers, voltage regulators, and switches. They also may work on traffic lights and street lights. To become proficient, most line installers and repairers require technical instruction and long-term on-the-job training. Apprenticeships are common. Employment of line installers and repairers is projected to grow 7 percent from
